UNITED STATES PATENT OFFICE.

JOSEPH F. HIBNER, OF HAMILTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE AUTOMATIC CASHIER CORPORATION, A CORPORATION OF VIRGINIA.

SUBTRACTIVE MONEY-CHANGER.

Application filed October 8, 1913.

To all whom it may concern:

Be it known that I, JOSEPH F. HIBNER, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Subtractive MoneyChangers, of which the following is a specification.

In the ordinary money-changing device a coin of given value is placed in the machine or paper money of given value is charged to the machine and the machine delivers change to the full amount.

My machine contemplates the sale of one or more things at a given unit of value and the return to the purchaser of the proper change due from the deposit of a given coin. In other words, the purchaser places the minuend in the machine; the subtrahend is retained and charged in the machine; and the remainder is disgorged for the purchaser. To illustrate :Assume the articles to be sold to be admissions to a place of amusement, the price of admissions being five cents each. I am exemplifying my invention in a machine designed for dealing with these five cent unit prices, for receiving from the purchaser single coins of the value of five, ten, twenty-five or fifty cents; for retaining in the machine the value of the number of admissions wanted, up to the limit of five; and for returning to the purchaser such change as may be proper, the change being delivered from a magazine and in the most advantageous grouping of coins.

Described in the briefest manner the exemplifying device embodies a magazine consisting of vertical tubes adapted for the coins to be dealt with, there being a fivecent tube, ten cent tube, twenty-five cent tube, and a fifty cent tube. The magazine is detachable and is placed in the machine loaded with such number of coins as may be suitable for beginning the days work; above each tube is a coin-receiving throat of proper size; a coin deposited by the purchaser is arrested in the throat; the cashier works a selected unit-key, selected according to the number of admissions wanted; the deposited coin is lowered in the throat; if the value of the number of admissions wanted equals the value of the deposited coin then the transaction is over and the number of admissions has been recorded on Specification of Letters Patent.

Serial No. 794,062.

certain counting mechanism in the machine. If, however, there is change due the purchaser, the movement of the selected unitkey will bring about the disgorging of that change. In the exemplifying machine the greatest number of unit-value admissions which can be dealt with is five; the largest coin which can be received is fifty cents; conveniently the machine is provided with a mechanism having the ordinary moneychanging function in order that the purchaser may present to the cashier a dollar and receive two half dollars in change so as to be in possession of a coin suited to the receiving capacity of the machine. The machine is provided with appropriate counting devices and with mechanism for performing various locking functions to secure integrity of action. To shorten the number of words likely to be found repeated in describing the exemplifying machine, I will refer to the above-mentioned coins as nickels, dimes, quarters and halves.

The machine comprises a finger-lever for each value coin the machine is adapted to receive and it also comprises a set of fingerkeys, each being appropriate to a given number of units of purchase. In considering this specification and its drawings con stant care should be exercised to avoid looking upon the unit-value keys as being coinvalue keys.

In describing my machine I will, as far as practicable, treat independently its main component devices, and in doing so I will treat those component devices in the order of :First, the magazine, including its construction and the features by means of which the magazine is locked in the machine and the features by means of which the magazine is closed to retain its load while the magazine is out of the machine; second, the means, broadly considered, for withdrawing coins from the base of the magazine for delivery to the purchaser; third, the dollar change-making element of the machine; fourth, the throat or slot features for receiving the deposited coins and for causing them to reach the magazine; fifth, the means by which the throat features transmit to the change-determining and change-delivering mechanism the indication of what this latter mechanism is to do; sixth, the change-determining and changedelivering mechanism; and seventh, such accessory features as may not have been previously explained with sufficient fullness.

My invention will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1, is a perspective view of an exemplifying machine: Fig 2, a front elevation with casing omitted: Fig. 3, a side elevation: Fig. 4, a front elevation of the magazine: Fig. 5, a side elevation of the magazine: Fig. 6, a vertical section of the dimetube on line b of Figs. 2 and 4: Fig. 7, the same, plus the lifting-plunger: Fig. 8, a vertical section of the magazine support on line a of Figs. 4 and 9: Fig. 9, a horizontal section of magazine-tubes on line 0 of Figs. 2, 3 and 4: Fig. 10, a vertical section of the base on line d: Fig. 11, a plan of part of the base, etc.: Fig. 12, a diagrammatic front elevation of stop-plate, etc., part vertical section on line 6 of Figs. 3, 13 and 15: Fig. 13, a vertical section of the nickel-throat on line f of Figs. 2, 12, 14 and 15: Fig. 14, a front elevation of the nickel-throat: Fig. 15, a plan of the throat-mechanism: Fig. 16, a diagram of the stop-bar system with parts in section on line 9 of Figs. 19 and 20: Fig. 17, a plan of part of the change-plate: Fig. 18, a front elevation of one of the fulcrums 83 of Figs. 19 and 20: Fig. 19, a plan of the base-work, part horizontal section, on line 0: Fig. 20, a fore-and-aft section of the basework on line b of Figs. 4, 9 and 19. Fig. 21, a plan of the base-work with top-plate omit ted: Fig. 22, a plan of the plate: Fig. 23, a front elevation of the plate: Fig. 24, a side elevation of the plate, part section on line it of Fig. 22: Fig. 25, a vertical section of unit-shafts on line i of Fig. 21: Fig. 2G, a side elevation of the three-unit bar: Fig. 27, a plan of the same: Fig. 28, a plan of the count-shaft and main counter: Fig. 29, a vertical section of a unit-head on line of Fig. 27: Fig. 30, a side elevation of the main counter: Figs. 31, to 35, inclusive, side elevations of the count-pawls: Fig. 36, a front elevation of the quarter-blades: Fig. 37, a side elevation of the stop-plate latch-lever: and Fig. 38, a "ertical section of the drawer, on line m of Fig. 21.

It should be here explained that a given figure of drawing designed particularly for use in explaining a given sub-mechanism of the machine, features not pertinent to this sub-mechanism may have been omitted, a plan leading to simplification of delineation and description. Vith the exception of Fig. 1 the inclosing casing of the machine has been omitted.

In the description I will frequently call attention, parenthetically, to a particular figure of the drawings, but it is to be understood that the given feature may appear in a number of the figures and that the one referred to is merely the one upon which the eye may be preferably rested for the instant.

The magazine.--In the drawings:-1, indicates general fixed frame-parts, particular members of which may be later specifically referred to: 2, (Fig. 10) a plate disposed across the top of the base portion of the machine, the front portion of this plate serving for the support of the magazine: 3, (Fig. 4) a magazine base-plate resting separably upon the front portion of plate 2: 4, a vertically disposed nickel magazine tube having its base fixedly secured in base-plate 3, this magazine tube being of a size suited for the reception of nickels: 5, 6 and 7, the magazine tubes for the dimes, quarters, and halves, respectively, these tubes being mounted in magazine baseplate 3 parallel with the nickel tube 4: 8, the magazine as a whole: 9, a discharge aperture extending down through plate 2 a short distance in front of the magazine tubes, the purpose of this aperture being to permit change-coins, pushed forward from the bases of the pile of coins in the magazine tubes to drop out of the machine and become accessible to the customer: 10, a rearwardly sliding finger mounted in the front portion of magazine baseplate 3, at the front of each tube, and adapted to slide back into the base of the tube: 11, a bar extending across the front ends of all the fingers 10 and rigidly secured to those fingers: 12, movable dowels engaging through the bar 11 and through magazine base-plate 3 and engaging apertures in plate 2, the pur pose of these dowels being to lock the magazine in inward working position upon plate 2, to lock fingers 10 in normal outward idle position and, also, to lock the fingers 10 in inward position when those fingers are pushed into the tubes: 13, a pile of dimes in dime tube 5: 14, a magazine top-plate fixedly secured to the upper ends of the tubes: 15, fingers mounted in magazine top-plate 14 and adapted to slide rearwardly into the tubes: 16, a bar extending along this series of fingers and uniting them: and 16, a dowel cooperating with bar 16 and magazine top-plate 14 and serving in holding fingers 15 in normal outward idle position or in holding them in inward working position within the tubes.

The tubes are open at their upper and lower ends and are provided with sightholes by means of which the piles of coins within the tubes may be inspected to determine that the tubes are initially sufficiently loaded for the beginning of the days work and that they have not become, in the course of the days work, so overloaded as to choke the machine.

The magazine as a whole may be handled separately from the machine and may be loaded and set away or placed in the machine, and more than one of the magazines may be provided for a given machine.

The magazine being out of the machine, lower fingers 10 are pushed into the tubes, furnishing a floor for each tube, and the upper fingers 15 are to be in withdrawn position so as to leave the upper ends of the tubes open. Under these conditions the tubes are to be charged with a sufficient number of appropriate coins for initiating the days work. When this has been done the upper fingers 15 are to be slid rearwardly in the tubes, under which circumstances the coins are entirely inclosed within the tubes and the dowels prevent the forward displacement of the fingers.

\Vhen the loaded magazine is to be placed in the machine it is to be slid rearwardly over the front edge of plate 2 to working position, and under the top plate 26 forming a part of the frame of the machine. This top plate has a coin slot in it over each tube. \Vhen the magazine has been placed then fingers 15 are to be withdrawn forwardly to idle position, and similarly with fingers 10, dowels 12 serving to lock fingers 10 in withdrawn position and to lock the base of the magazine to plate 2. The magazine is now ready to receive coins dropped into its tubes through the slots in the upper frame-plate and to have coins expelled forwardly from the bases of the piles of coins in the tubes.

As fingers 10 are not at the extreme bases of the tubes, and as they are, when pushed rearwardly, to form floors for the tubes, and as the piles of coins extend to the bases of the tube it becomes necessary to lift the piles of coins in order that fingers 10 may enter the tubes. Mechanism for this lifting purpose will now be described.

Proceeding with the drawings :17, (Fig. 7) indicates an upwardly movable plunger in plate 2 at each tube of the magazine: 18, a spring coacting with each of these plungers to hold the plungers down so that their upper ends will be not higher than top plate 2: 19, a lifting-shaft disposed across the frame of the machine in front of and below the magazine: 20, lifting arms fast on shaft 19, one of these arms projecting under each of plungers l7: and 21, a crank upon the lifting shaft.

Vhen the magazine is to be removed from the machine, the plungers 17 are raised, by the lifting mechanism in an obvious manner, thus elevating all of the piles of coins in the tubes and permitting fingers 10 to be moved back into the tubes. Fingers 10 have their rear portions slotted to straddle plungers 17 as the fingers move inwardly. If, for any reason, it be desired to remo e the magazine from the machine without improperly delaying the continued use of the machine, such delay may be avoided by merely substituting another properly loaded magazine.

Coin-delivering means, broadly 00mmered.I will now describe, broadly, the illustrated means for withdrawing coins from the base of the magazine for delivery to the purchaser, and in this connection it may be well to determine on the term purchaser as defining the party who deposits a coin and receives change if any is due 3 him, and the term operator as defining the party who has charge of the machine.

Proceeding with the drawings :22, (Fig. 9) indicates shallow grooves in the upper surface of frame-plate 2, one of these grooves being disposed under each of the magazine tubes and over its coin-delivery hole 9 in the frame-plate; 23, a delivery blade fitted to slide forward in the groove below the dime tube, this blade having a thickness suited to that of a dime; 24, a similar delivery blade disposed in the dime groove below delivery blade 23, there thus being two dimcblades one disposed above the other; 25, a. similar delivery blade under the nickel tube; 26, the top frame-plate which has been heretofore referred to; 27, the delivery-blade under the quarter-tube; 28, holes extending down through the delivery blades near their forward ends under the delivery tubes, except in the case of the quarter tube, it being understood that the delivery-blades are of a thickness to suit the coins to which they pertain and that the holes 28 in the blades are of a size to freely receive the coins from their tubes; 29, (Fig. 19) the delivery-blade below the half-dollar tube; 30, a spring co-acting with delivery-blade 29 to hold it in normal rearward position with its receiving hole 28 under its 3 tube; 31, open pouches at the front of the machine, their rear portions being in communication with the delivery openings 9, the exemplification showing one of these pouches for the half-dollar tube and another pouch adapted to receive coins from the remaining tubes, these pouches permitting the purchaser to easily take possession of the change delivered to him by the machine; and 32, the general base-portion of the machine on which the magazine rests.

Looking at Fig. 7, and assuming a pile of dimes to be within dime-tube 5, that pile rests on frame-plate 2 forming the floor of the tube. the holes 28 of the delivery-blades. If, now, by any means whatever, the lower deliveryblade 24 be pushed forward, to the left, the lowermost dime will be pushed forward from the bottom of the pile and drop through delivery hole 9 and into the front pouch where the customer can get it. If, however, both of the dime blades be pushed at once then two dimes will be pushed out from under the pile and will drop into the The two lowermost dimes rest in a pouch. It may be here stated that the upper dime blade will never be pushed alone. The lower dime blade will be pushed alone, as when a dime and a nickel are needed for change. Both dime blades will be pushed together when two dimes are needed for change.

The dime tube only is provided with double blades, the other tubes being provided with single blades. The particular mechanism for determining which of the deliveryblades shall move, and the mechanism for moving them, will be later described.

T he half -(ZOZZa1' change-maken-The largest coin the particular machine illustrated is designed to deal with is a halfdollar, and if a customer has a dollar the machine provides facilities by which the operator may give him two half-dollars for it.

Proceeding with the drawings :33 (Fig. 11) indicates a projection from the upper surface of the half-dollar delivery-blade 29, which blade is of a thickness to receive two halfdol]ars from the half-dollar tube: 34, a finger-lever pivoted on the frame: 35, a spring holding this lever to idle position: 36, a flipping toe on the inner end of the lever, this toe being adapted to come in contact with the rear surface of projection 33 when the outer end of the lever is swung rearwardly: 37. a spring holding the toe to normal position as a prolongation of the lever: and 38, a counter for registering the impulses of the half-dollar delivery-blade. each impulse corresponding with the withdrawal of two half dollars from the halfdollar tube.

In subtractive change-making operation of the exemplifying machine a half-dollar is never delivered to the customer as change, for the exemplifying machine is not designed for the subtractive changing of any coin larger than a half-dollar. If the customer hands the operator a dollar the operator may retain this dollar or place it in a money drawer, and, by pulling back upon lever 34, he pushes two half-dollars from the base of the pile in the half-dollar tube and they are delivered into the half-dollar pouch where the customer can get them. The customer may then put one of these half-dollars in the half-dollar throat of the machine. and, upon the regular operation of the machine, get back such change as may be due him from that half-dollar. lVhen the operator pulls back upon lever 34 its toe end pushes the delivery-blade forward a suflicient distance to effect the delivery into the pouch, and when the blade has moved this distance the toe of the lever clears projection 33 and the blade retreats to normal position and the pile of half-dollars settles so that the blade again contains two halfdollars. When lever 34 is released its spring returns it to normal position, the flipping of the toe permitting this movement in an obvious manner. Counter 38 indicates the number of pairs of half-dollars which have thgs been withdrawn from the half-dollar tu e.

Throat 0r slot features.-In the upper portion of the machine there is a vertical throat over each magazine-tube, the horizontal cross-section of these throats being adapted for the coins for which the several magazine-tubes are appropriated. Each threat has a series of movable stops adapted to project into it and arrest the deposited coin at various stages of descent, mechanism being provided by which these stops are removed in proper order to permit the coins to go in proper time to the magazine-tube.

As the four throats, with their stops are alike, I will explain the matter in the singular with reference to the nickel throat.

Referring to the drawings, and particularly to Figs. 12 to 15, inclusive :-39, indicates a fixed top frame'bar some distance over frame-bar 26, these two bars forming a fixed skeleton top structure: 40, columns, connecting this top structure with the base structure of the machine and leaving space for the reception of the magazine in the manner before explained: 41, a vertical nickelthroat carried by the skeleton top structure above the nickel magazine, it being understood that the skeleton top structure carries a similar throat for the dimes, quarters and halves: 42, an endwise movable stopplate disposed at the rear of the throats: 43, links suspending the stop-plate from the top frame-bar 39 and typifying means by which the stop-plate is guided in its endwise movements: 44, a stop-pin projecting forward from the stop-plate and across the throat and adapted, as the stopplate is moved endwise, to take coin-arresting position inside the throat or to move aside to non-arresting position, this stoppin being hereinafter referred to as the first stop: 45, a lever pivoted near the throat and having a toe projecting into the side of the throat, in coin-arresting position, this toe being hereinafter referred to as the second stop, this second stop being located at the edge of the throat opposite first stop 44 and on a lower level: 46, a stop-pin projecting forwardly from the stop-plate, at the same edge of the throat as first stop 44 and on a lower level than second stop 45, this stop 46 being hereinafter referred to as the third stop: 47, a stop-pin projecting forwardly from the stop-plate at the same edge of the throat with the second stop and on a lower level than third stop 46, this stop 47 being hereinafter referred to as the fourth stop: 48, a spring urging the stop-plate endwise so that first stop 44 and third stop 46 will be in non-arresting position while fourth stop 47 is in arresting position within the throat: 49, a spring actuated latchle er extending up from the change-determining and change-delivering mechanism in the base of the machine and adapted to latch the stop-plate when the stop-plate is moved to the left: 50, an arm pivoted at the throat, near its upper end, and projectinginto the edge of the throat, opposite first stop 44: 51, a spring urging this arm to its upper position: 52, a finger-lever by means of which arm 50 may be moved downwardly in the slot: 53, a pin projecting rearward from the finger-lever: 54, a coin-indicating rod extending from near pin 53 down into the change-determining and change-delivering mechanism, this rod being adapted for vertical motion and also adapted to have its upper end swing sidewise: 55, a downwardly presenting hook on the upper end of the coin-indicating rod, this hook being above pin 53 and to one side of the pin: 56, the latching end of latch-lever 49, this latching end being adapted, when the stop-plate moves to the left, to engage behind a portion of the plate and retain the plate in its leftward position until the latch is released: 7, a pin projecting from stop-lever and adapted, as the second stop formed by this lever moves downward in the slot, to engage against the right-hand edge of coin-indicating rod 54: 58, slots through the walls of the throat to permit of the play of the stoppins: 59, a downwardly presenting shoulder formed in the rear wall of the throat just over the toe of arm 50, the throat being staggered at this shoulder so that the front portion of the throat is forward of the rear portion: 60, the bevel or curved inner surface of the front wall of the throat, where the throat offsets rearwardly: 61, an open front for an intermediate portion of the throat, this open front having a width not quite equal to the width of the throat: 62, a handle by means of which the stop-plate may be moved to the left; and 63, a pin projecting from coinindicating rod 54 through the stop-plate and adapted, when the upper end of the coin-indicating rod is swung to the left, to shift the stop-plate to the left.

lt is to he understood that Fig. 12 is of a diagrammatic character with a number of merely structural features omitted, such for instance, as the skeletonizing of the stopplate to permit of more ready assembling and inspection of parts in the practical machine. This has been done for the purpose of simplification in the explanation of the functional features of the machine. Again, in Fig. 12 only the nickel throat mechanism has been shown, the position of the other throats being indicated by dotted vertical lines. This, also, tends toward simplifica 66 ties. in explanation,

Assuming that the machine, so far as its throat-work is concerned, is empty, business with the machine not having yet been begun, finger-lever 52 may be worked up and down freely, the inner end of arm working up and down with the finger-lever. if, now, a nickel be dropped into nickelthroat 41 it will pass down and be deflected reaiwrardly by the ofiset in the throat and will take position on the second stop formed by the inwardly projecting toe-lever 45. The nickel at this time will, as it rests on the second stop, have its upper edge under the toe of arm 50 which projects into the slot. The nickel has been deposited in the throat but nothing has occurred further than the descent of the nickel to a point well down in the throat, as determined by a second stop 45. In this position the nickel may be inspected, it being understood, of course, that the material of the throat-walls will be of a character to permit of such inspection or that the walls, if opaque, will be provided with appropriate sight holes. If, now, finger-lever 52 be depressed, the toe of arm 50, engaging over the nickel, will force the nickel downward in the slot, and this move' ment of the nickel will cause the toe of lever 45 to swing aside and permit the nickel to drop further. But as lever 45 swings to the left, its pin, 57, swings coin-indicating rod to the left and, through the medium of pin 63, moves the stop-plate to the left, in which forward position the stopplate is latched by latch-lever 49. This movement of the stop-plate has moved third stop-pin 46 edgewise into the throat and the nickel has become arrested. It is at this stage of the operation of the machine that the change-determining and change-delivering mechanism in the base of the machine is to be operated, as will be hereinafter described, such operation bringing about a registration of the nickel which has been deposited, this same operation serving to release latch-lever 49 (see Fig. 37) and permitting the stop-plate to go again to the right, this rightward movement of the stopplate causing third stop 46 to move out of the throat while fourth stop 47 moves into the throat, thus permitting the nickel to descend a stage further. This is the end of the transaction with the nickel in question, the nickel remaining supported on fourth stop 47 until a later operation of the stopplate permits the nickel to drop to the nickel-tube of the magazine. \Vhen a second nickel is dropped into the throat it goes through the same course as the first nickel, the leftward movement of the stop-plate withdrawing fourth stop 47 from the throat and permitting the first nickel to drop into the magazine tube. In the ordinary course of the working of the machine, there will therefore alwaysbe a nickel resting on fourth stop 47, prior to its going to the magazine, and there may be a second nickel resting on second stop 45 prior to the actuation of the finger-lever which forces the upper nickel down and permits the lower nickel to drop to the magazine-tube. If, while the nickel is resting on third stop 46, another nickel be dropped into the throat, it will not descend, being arrested by first stop 44, and this other nickel can take position under lever 50 only after the change determining and change-delivering mechanism in the base of the machine has been operated for the first nickel and has unlatched the stop-plate. It will, of course, be understood that under the assumed conditions of the purchase Whose unit value is a nickel there will be no change delivered. If it happen that a dime be inadvertently dropped into the nickel throat it will pass out of front opening 61 and drop upon the forward portion of plate 26 where it may be recovered, and this will apply in case any coin be inadvertently dropped into the throat belonging to the larger coins, and it may be said that the explanation made of the regimen of the coin in the nickel throat will apply equally to coins in the other throats.

Attention has been called to the fact that after dealings with the machine are under way there is likely to be a coin held in the coin-throats, such coins not goingto the magazine until at a later impulse of the machine. When the magazine is to be removed from the machine, as for auditing purposes, all the throats should be cleared and such coins as thev may contain should go to the magazine. To provide for this, it is only necessary, before removing the magazine from the machine. to manipulate handle 62- so as to shift the stop-plate to the left, such action causing the emptying of all of the throats.

Attention has been called to changeindieating rod 54 pertaining to the nickel throat, but it will be remembered that no function has been ascribed to this rod other than that of causing the leftward shifting of the stopplate. A further. and the important function of the coin-indicating rod.may be paren thetically referred to in a brief wav. Vhen finger-lever 52 is depressed to push a nickel down, as has been explained. the upper end of coin-indicating rod 54 is pushed to the left by pin 57. This brings hook 55 over pin the result being that. as the impression of the finger-lever continues. the coinindicating rod is temporarily lifted. This lifting motion of the coin-indicating rod operates on the change-determining and change-delivering mechanism in the base of the machine in a manner appropriate to the reception of a nickel. So, also, with the coin-indicating rods of the other throats.

The details of this matter will be later explained with fullness.

In connection with Fig. 12 it was eX- plained that the operation of finger-lever 52, in forcing the nickel down in the throat, lifted coin-indicating-rod 54, this lifting being effected by pin 5; of the finger-lever engaging hook 55 of the coin-indicating rod, and the construction was such that the coin indicating rod would stay up as long as the finger-lever was depressed. The other finger-levers transmit the lifting motion to their coin-indicating rods by a somewhat different mechanism in order that after the coin-indicating rod has been properly lifted, a. letgo device will disconnect it from the finger-lever and permitthe coin-indicating rod to drop to normal position. The purpose of this arrangement will now be 8X plained:-

Proceeding with the drawings (see Fig. 16) :63=*, indicates a change-measuring plate, disposed in the base of the machine and having a fore and aft motion in the frame, and also a selective transverse motion, as Will be later explained with fullness: 64, a one-unit bar arranged to slide fore-and-aft in the machine and give proper fore-and-aft motion to plate 63 by means to be described later: 65, a similar two-unit bar: 66, a similar three-unit bar: 67, a similar four-unit bar: 68, a similar fiveunit bar, each of these bars having a notch in its upper edge: 69, a lock-bar disposed across the machine over the five unit-bars and having its lower edge engaging the locknctches in the unit-bars so as to normally prevent their endwise motion, lock-bar 69 being capable of endwise motion and held to its leftward normal position by a spring: 70, a notch in the lower edge of the lock-bar in such position that, when the lock-bar is shifted a certain distance endwise to the right, one-unit bar 6i will be freed from the domination of the lock-bar and be able to move endwise: 71, a similar notch to release two-unit bar when the lock-bar is shifted a still further distance to the right: 72, 73 and 74, similar notches in the lock-bar serving, when the lock-bar is shifted a certain distance to the right. to free the threeunit bar and the four-unit bar and the fiveunit bar: 75, a shaft in the base of the machine: 76, an arm mounted on this shaft and having pivotal connection with the lower end of nickel-indicating rod 54;: 77, a toe-cam fast on shaft 75: and 78, a lug projecting from the face of lock-bar 69 and engaged by cam 77 and having a notch adapted to be engaged by the toe of the cam.

Upon depressing the nickel finger-lever and thus lifting nickel indicating-rod 54, as has been heretofore explained, the rising of the rod causes cam 77 to push the lockbar to the right until one-unit bar 64 is freed from the domination of the lock-bar. toe of the cam catches in the notch of lug 78 and the lock-bar remains in its position of release as regards one-unit bar 64, and this condition will continue until some subse quent endwise motion of the lock-bar to the right shall release the toe of the cam, thus permitting the weight of rod 54 to take cam 77 down to normal position. It is thus seen that the nickel indicating-rod 54' acts on the lock-bar regardless of the plate movement. As five cents is the purchase unit of the exemplifying machine, the operation of the nickel-delivery mechanism manifestly calls for no change. Nickel-indicating-bar 54 therefore has no adjusting connection with change-measuring-plate 63 The other coin-indicating bars operate on that plate, to shift it sidewise, and through it effect the proper shifting of the lock-bar to release the appropriate unit-bars.

Proceeding with the drawings (Fig. 16) :79, indicates the dime-indicating rod extending between the upper and lower portions of the machine: 80, a similar quarterindicating-rod: 81, the half-indicatingrod: 82, a rack having its lower end pivoted to dime-indicating-rod 79, the quarter indicating-rod and the half-indicating-rod being provided with a similar rack: 83, (Fig. 18) a fixed fulcrum at the left of each rack, on which the rack may rock and on which it may slide vertically: 84. the teeth of the rack: 85, a segment carried by each of the finger-levers, except the nickel-lever: 86, a knockout carried by each segment and adapted, when the segment has engaged its rack and carried it up a certain distance, to force the rack out of engagement with the segment and permit its indicating-bar to drop: 87, a tripping-arm fast with each of the second stops 45 in the throat, except as to the nickel throat: 88, a shaft disposed fore-and-aft at the base of the machine: 89, an arm fast on this shaft and pivoted to the lower end of dime-indicating-rod 79: 90, a lug projecting down from the-changemeasuring plate 63: 91, an arm projecting from shaft 88 and adapted, when the dime indicating rod 79 is lifted to engage lug 90 and shift the change-measuring plate to the right to a certain degree: 91*, a pin projecting up from the lock-bar: and 91", a wedge carried by the plate and cooperating with the pin as the plate moves forward or as the plate moves sidewise.

\Vhen the dime finger-lever is depressed, to push a dime down in the dime-throat, the arm 87 pushes the upper end of dime-indicating rod 79 to the left causing the dimerack to engage the dime segment at a certain stage in the rising of the segment, this action lifting the dimeindioating. rod 79 The and causing arm- 91 to push change-measuring plate 63 to the right a certain distance. This sidewise shifting of the change-measuring plate will, through the medium of wedge 91, move the lock-bar endwise to the proper degree to free the two-unit bar from the domination of the lock-bar. \Vhen the dime-indicating bar 79 shall have been lifted and has performed the oflice mentioned, the continued depression of the dime fingerlever causes the rack to disengage and the dime-indicating bar to descend to normal position, devices to be later explained serving to lock the change-measuring plate in its shifted position to the right.

The unlocking movement of the lock-bar, which has just been described with reference to the two-unit bar, was effected by the side shifting of the change-measuring plate as effected by the dime-indicating rod 79 and, as has been stated, locking devices will be described for locking the change-measuring plate in its adjusted sidewise position prior to its making its forward trip. As a nickel calls for no change, and as nickel-indicating rod 5% effects no sidewise shifting of the change-measuring plate, the rod itself shifts the lock-bar, as has been explained. and later, when the change-measuring plate makes its forward stroke wedge 91 shifts the lock-bar endwise suificiently to release the toe of cam 77. The wedge performs its function as a wedge only in effecting the release of the toe-cam 77, its function in moving the lock-bar sidewise under the influence of other coin-indicating rods, being merely that of a sidewise pusher as the change-1ueasuring plate is shifted to the right.

A schedule of the amount of change which may be called for from various coins will be later presented but attention may here be called to the fact that a quarter need never be disgorged from the machine except in making change for a half-dollar. This fact permits of the consolidation, so to speak. of the mechanism by which the quarter-ind cating rod and the half-indicating rod shift the change measuring plate sidewise.

Proceeding with the drawings (Fig. 16) z- 92, indicates a shaft below the changemeasuring plate: 93, an arm fast on this shaft and pivoted to the lower end of the quarter-indicating rod 80: 9l, a lug projecting down from the change-measuring plate: 95, an arm fast on shaft 92 and adapted to engage lug 9l and shift the change-measuring plate to the right: 96, another shaft mounted below the change-measuring plate: 97, an arm fast on this shaft and pivoted to the lower end of the half-indicating rod 81: 98, an arm fast with arm 97: 99, an arm fast with arm 93: and 100, a link connectingarms 98 and 99 and slotted so that arm 99 may oscillate to the right without oscillating arm 97.

If the quarter-finger-lever be depressed, the change-measuring plate will be shifted sidewise to the right an appropriate distance, and the lock-bar will, at the same time, be shifted to the right such distance as to unlock all of the unit-bars. If the half finger-lever be depressed the result produced in the shifting of the change-measuring plate and the lock-bar will be precisely the same as when the quarter finger lever be depressed.

"hangs-determining and change-deutering mechanism.1t has been explained that, a given coin having been placed in the proper throat and its finger-lever manipulated, a coin-indicating rod was lifted. The lifting of this indicating-rod sets certain mechanism in the parts of the machine, appropriate to the deposit of the given coin, and then, upon manipulating a key pertinent to the number of unit purchases, the change-delivering mechanism will become adjusted for delivery of the proper change and, upon further manipulation of that key, the proper change will be delivered into the pouch.

Briefly explained, plate 63' is disposed below the delivery blades; this plate carries a number of vertically movable pins to cooperate with the blades; these pins are normally down and free from the blades; the sidewise adjusting of the plate. as determined by the coin-indicating rods, sets the plate in such position that appropriate pins will be in position to rise and enter holes in the rear portions of the blades; the first movement of a selected unit-key elevates the appropriate pin or pins, whereby the plate becomes connected to the proper blades; the further movement of the key pushes the plate forward, and with it the proper blades, thus delivering the proper coins to the pouches; the blades and plate and pins all return to normal position when the fingerkev is released.

Proceeding with the drawings, and particularly Figs. 19 to 25, inclusive 101, indicates a carriage adapted to slide back and forth in the top of the base, this carriage supporting the plate 63 in such manner that it may slide sidewise: 102, an index-lever mounted on the plate and having a tooth adapted to engage selective notches in the carriage when the plate is shifted sidewise, this index-lever being provided with a spring urging it into engagement with the notches: 102 the notches in the carriage, these notches being adapted to be engaged by the index-lever and, in the illustrated machine, being two in number, the indexlever being normally out of engagement with eithernotch: 102, a fixed pin in the top of the base, adapted to engage and trip the index-lever when the carriage has moved the plate forward its full functional distance: 103, springs urging the carriage and plate to normal rearward position: 104, a spring urging the plate to normal leftward position in the carriage, it being understood that in this description the reader is assumed to be standing in front of that por tion of the machine from which project the pouches, this portion having been heretofore referred to as the front of the machine: 105, springs urging the several delivery-blades to their normal rearward position as determined by suitable stops carried by top-plate 2: 106, a group of fingerkeys projecting out from the rear of the base of the machine, there being a key for a one-unit purchase, another for a two-unit purchase, and so on up to five-units of purchase: 107, a vertically movable blade-pin carried by the plate under the nickel-blade: 108, a second similar blade-pin under the nickel-blade: 109, a third similar blade-pin under the nickel blade: 110, a cross slot in the nickel-blade to cooperate with pin 109 when the plate is moved properly to the right and the pin projected up into the slot: 111, a similar slot to cooperate with pin 108: 112, a similar slot to cooperate with pin 107, this slot having a forward extension widened at its front portion: 113, a blade pin carried by the plate under the dimeblades: 114, a second similar pin under the dime-blades: 115, a third similar pin under the dime-blades: 116, a cross slot in the lower dime-blade 24 and adapted to co operate with pin 115: 117, a cross slot in the lower dime-blade and adapted to cooperate with pin 114: 118, a cross slot in both dimeblades adapted to cooperate with pin 113: 119, a fore-and-aft slot in the upper dimeblade to prevent the upper dime-blade being pushed forward if pin 114: or 115, in being projected upwardly to actuate the lower dime-blade, should project up too far, this slot 119 being a mere precaution against inaccurate workmanship: 120, a blade-pin permanently projecting from the plate through quarter-blade 27: 121, a crossslot in the quarter-blade to cooperate with pin 120: 122, a fore-and-aft slot in the quarterblade to provide for the normal forward movement of pin 120 without moving the quarter-blade: 123, a top quarter-blade arranged fore-and-aft at right angles to quarter-blade 27: 124, an aperture in the left-hand end of the top quarter-blade and normally positioned directly under the quarter-magazine tube and in line with but to the right of aperture 28 in quarter-blade 27 and normally charged with a quarter from the quarter-tube: 125, a one-unit shaft mounted in the base of the machine across under the nickel-blade: 126, a two-unit shaft crossing under the nickel-blade and dimeblade: 127, a three-unit shaft crossing under the dime-blade: 128, a four-unit shaft crossing under the nickel-blade: 129, a fiveunit shaft in the base of the machine,this shaft being); illustrated as being in line with two-unit shaft 126: 129*. an arm fast on each unit-shaft and pivotally connected with the appropriate unit-rod, each unit-rod being in two endwise sections pivotally united at their junctures with their arms 12%: 130, a one-unit finger-key: 131, a two unit finger-key: 132, a three-unit finger-key: 133, a four-unit finger-key: 134:, a five-unit finger-key, each of these unit-keys being in the form of a bell-crank having its short arm pivotally connected to the rear end of the appropriate unit-bars 64:, etc.; 135, springs for holding these keys normally in elevated positions: 136. a head on the forward end of each of the unit-bars 6 1, etc., the forward ends of the unit-bars being pivoted in these heads: 137, a guide-stem on the forward end of each of the heads, these stems sliding in apertures in the front wall of the base and forming guides for the front ends of the unit-bars: 138, 139, 140, 1 11 and 142, lugs projecting from the lower face of plate 63*, these lugs occupying various positions under the plate and presenting rearward faces by means of which impelling agents may engage and push the plate forward: 143, impelling arms fast on shafts 125, 126, 127, 128 and 129 and having such form and position that when a selected shaft is rocked the end of the arm will engage an appropriate one of the lugs projecting down from the plate and move the plate forward: 14 1. a spring flipping end provided upon the arm 113 of one-unit shaft 125 to provide that this arm may continue its for ward motion after the plate comes to rest and to provide that the arm may retreat past lug 1 12: 14.), a downwardly presenting shoe on the lower end of each of the bladepins 107, etc. these shoes extending foreand aft. each of the blade'pins. except 120, being provided with a spring holding the pin downward out of engagement with the blades: 1413, a cam on unit-shaft adapted. when the shaft is rocked. to engage the shoe of pin 107 and push that pin upward into engagement with its slot in the nickel.- blade. providing. however, that the plate is in such sidewise position of adjustment that the shoe in question will be over this cam: 117. a second cam on one-unit shaft to coiiperate with blade-pin 113: 148, a cam on the two-unit shaft, to cooperate with blade pin 114: 14-), a second cam on two-unit shaft 126 to cooperate with pin 109: 150. a cam on the three-unit shaft to cooperate with bladepin 115: 151, a cam on the four-unit shaft 128 to cooperate with pin 109;

Quarter Quarter Quarter 3 Quarter Quarter Hi I i 1 quarter. nnr a, 1 dimes Half v Z llalf 2. t. ,1 1 3;? 11 quarto lhaf 4 U m-tkel Half v 5 Notice that a half-dollar is never deposited in the machine unless at least a quarter is coming back in change, and also that a quarter is never received in change unless a half-dollar has been deposited. This fact which permits of the consolidation of some of the mechanism pertaining to the halfdollar and quarter throats, a consolidation which is not essential but which permits of a very material lessening of the number of parts involved in the change-determining and changc-delivering mechanism. The doubling of the quarter-blades also provides for the simultaneous delivery of all changecoins.

It is deemed advisable at this point to explain results in detail, leaving the explanation of the mode of operation of the detailed mechanism to be taken care of later.

In Figs. 19 to 25, inclusive, assume the throats of the machine all to be empty. Loch-bar (39 locks all the unit-l eys. Force a nic el down in the nickel-throat and the one-unit liev becomes unlocked and its actuation merely effects a one-unit registration on a main counter, and the striking of a bell. as will be later explained. The normal position of the carriage and plate is as in Fig. 19. and the mentioned actuation of the oneunit key nas merely moved the plate forward idly. All the movable pins in the plate are down out of engagement with the blades.

Force a dime down in the dime-throat. This moves lock-bar 69 to unlock the one-unit key and the two-unit key, and shifts the plate to the right to the first notch of 102 where the plate is retained by the index-lever 102. If, now, the two-unit key be depressed the plate will go forward and return idly, the bell will ring, and two-units will be charged on the main counter. If, however, instead of depressing the two-unit key, the one-unit key be depressed, pin 107 will rise and the nickel-blade will move forward with the plate and deliver a nickel change in the pouch.

If a quarter be forced down in the quarter-throat, the plate will be shifted to its third position, being the second notch of 102*, and all unit-keys will be unlocked. If the five-unit key be now operated, the plate will move forward idly as before. The plate, in moving forward under the condition stated, moves lower quarter-blade 2T forward, by the action of permanent pin 120, but this action is an idle one owing to the fact that hole 28 in the lower quarterblade contains no quarter, and this holds good with all of the forward movements of lower quarter-blade 27 under the influence of a deposited quarter. If, however, instead of operating the five-unit key, the four-unit key be operated, pin 109 will be raised and the nickel-blade will move forward with the plate and a nickel in change will be delivered. If, however, instead of the five-unit key or the four-unit key, the three-unit key be operated, pin 115 will be lifted and engage the lower dime-blade and that blade will move forward with the plate and a dime in change will be delivered. If, instead of either of the three previously mentioned finger-keys, the two-unit key be operated, pins 114 will engage the lower dime-blade and pin 108 will engage the nickelblade and those two blades will move forward with the plate, and a nickel and a dime change will be delivered. If, instead of either of the four keys previously mentioned, the oneunitkey be operated, pin 113 will engage the upper and lower dime-blades and those blades will move forward with the plate and two dimes in change will be delivered.

If a half-dollar be forced down in the half-dollar throat, the rising of half-dollar coin-indicating rod 81 will bring about several things. It will, by the rocking of shaft 96 (Fig. 21) shift the top quarter-blade 123 to the left and deliver a quarter to the coinhole 28 of the lower quarter-blade 27; it will shift the plate to its third position, being the second notch; it will unlock all the keys; pin 120 will have passed across slot 122 and be in position to move lower quarter-blade 27 forward when the plate moves forward. If. now, five-unit key be operated, pin 120 will push the lower quarter-blade forward and deliver a quarter in change. If, instead of the five-unit key, the four-unit key be operated, pin 120 will act on the lower quarter-blade and pin 109 will engage the nickel-blade and consequently the nickel-blade and the quarter-blade will move forward with the plate and a quarter and a nickel in change will be delivered. If, instead of the five-unit key or the fourunit key, the three-unit key be operated, pin 120 will act on the lower quarter-blade and pin 115 will engage the lower dimeblade, consequently when the plate moves forward the lower dime-blade and the lower quarter-blade will deliver a quarter and a dime in change. If, instead of either of the three mentioned keys being operated, the two-unit key be operated, pin 120 will act on the lower quarter-blade and pin 111 will engage the lower dimeblade, and pin 108 will engage the nickel-blade and, when the plate moves forward, the three blades will deliver a quarter, a dime, and a nickel in change. If, instead of either of the previously mentioned unit-keys being operated, the one-unit key be operated, pin 120 will engage the lower quarter-blade, and pin 113 will engage the upper and lower dimeblades and, consequently, these two blades will move forward with the plate and a quarter and two dimes will be delivered in change.

Lower quarter-blade 27 moves forward whenever the plate is to the right in the second notch but idly, as its coin-hole is empty. The transfer of a quarter from the quarter-tube to the lower quarter-blade is effected by the half-dollar coin-indicating rod, while the effectiveness on the nickelblades or the dime-blades is brought about by the sidewise shifting of the plate to bring proper pins over cams for elevating them to effective position.

When the plate is in the normal position of Fig. 19, lug 142 is in position to be engaged by impelling arm 143 of the one-unit shaft, and this is the case in any of the sidewise positions of the plate. But as regards the impelling-fingers on the other unit-shafts their appropriate lugs are normally to the side of them and take position to be engaged by the impelling-fingers only when the plate has been shifted sidewise. When any impelling finger pushes the plate forward, the plate, upon reaching the forward extremity of its stroke, becomes re leased by the index-lever and pin 102 and instantly shifts to the left to normal position, thus permitting the plate to return rearwardly to normal position regardless of the impelling finger which moved it forward. As the one-unit impelling finger requires to deal with its lug on the plate regardless of whether the plate be shifted sidewise or not, provision is made by means
